Letters Patent No. 84,074,1iated November 17, 1868.'

To all lwhom it may concern Be it known that I, JOHN W. WHEELER, of Cleveland, in the county of Cuyahoga, and State of Ohio, have invented a certain new and improved Machine for Spreading Paint, Mastic, Sto.; and I do hereby declare that the following is a full and complete description of the construction and operation of the same, `reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a top view ofthemaehine.

Figure 2 a longitudinal section.A

Figure 3, a view o i' the end. Like letters of reference refer to like parts in the diiferent views.

The nature of this invention relates to .a machine so constructed and arranged that any plastic material,

'as thick paint or mastic, can be spread upon cloth, pa-.

per, and other'like surfaces, smoothly, and of anniform thickness.

This machine consists of a frame A, figs. 2 and 3, provided 'with close sides, between which is journalled in s, G. y

inmediatelynnder the roller is a bed-plate, D, over which passes an endless belt or apron, E, moved or carlied vby a pair of rollers, -F F', one in each end of the frame, as shownin fig. 2.

The roller F receives motion from the speader or roller B, by means, of a belt, G, running in grooved pulleys, H, keyed to the shafts of the rollers F' and B, all of which are operated by the crank I.

J is a pair of supplementary sides or guards, placed against the sides of the frame, as shown in iig. 1, and under the lower edge of which the edges of the endless apron runs, and are pressed down upon the saine by the springs K, secured in the adjustable stays L, the purpose of which will'hereinafter be shown.

Having thus described the construction and arrangement of the machine, the practical use and operation of the same are as follows: l

It is Well known that paper, either impregnated or covered with some plastic tire and weather-proof Inaterial, is extensively used for roofing. When used as a mastic only, instead 'of a satnrating-compound, it is spread on the sheet with a trow'el constructed especially for that purpos--a work performed with great labor, much time, and hence expensive; also, -the work is not Well donc, as 'the material is not evenly laid on, it being thicker in some places than others, rendering the Work variable in thickness.

vTo avoid this expensive labor, this machine is` ina roller or spreader, B, in adj nstable standards or beartended, and operated thus:

A strip of paper of the required width is laid upon the apron at'X, referred to. The edges of lsaid cloth are madev to pass under the guards J, and the end brought to the face of the roller or spreader B. On

the cloth is now thrown the mastic or paint, filling that part of the frame near the spreader full, if need be. Now, on turning the roller in the direction of the arrow, motion will be given to the apron, that will carry .the paper or cloth laid thereon 'under the spreader, 'together with as much material as can pass with the under the roller -is not rolled upon, but pushed forward and ,upWa-rd, by the revolving motion ofthe roller, the

' result of which is that the material is spread evenly and smoothly upon the cloth or paper by the sliding and pressing action of the roller.

It will be obvious that, if the lower face of the. roller revolved in the saine direction that the apron moves, the mastic'would be drawn in under, and rolled upon, and pressed down upon the cloth, and that in an unequal, irregular manner, according to the condition of the mastic as it lay piled up against the face of the spreader. It would also stickto the face of the roller, lifting the material from thegpaper or cloth, incre or less, according to its adhesiveriess; but by giving this reverse movement to the spreader, the action of the face of the roller upon the mastic'is a'slidng one, and hence there can be no sticking of the mastic to its face; hence it .will be free, clean, and smooth at all times when .in operation, and should any stick tothe roller, it is scraped off by the scraper N. v

By causing'the edges of the strip of cloth or paper to be carried along undel' the guards J, that section covered thereby will not be impressed upon by the mastic, and hence will leave .the machine with a narrow edging or border nnplastcred along each side-of the cloth.

Though this machine is especially designed for spreading cement upon paper or cloth, to be used for roofing, it is equally well adapted to spreading the thick paint on cloth for ooring, and will therefore, applied to this branch of industry, save largely in the expense of the manufacture of that article, which, as ordinarily done, is tedionsly slow and expensive. A Y

The roller or spreader may be so arranged that it may work directly upon one of the end rollers, instead of upon a solid bed-plate, as above described; however, the latter way is preferable, it being more convenient, and. keeps the cloth straight lundr'the roller.

What I claim as my improvement, and desire to secure by Letters Patent, is-

l. The spreader or roller B, in combination with the apron E and rollers F F', when'operating conjointly and reversely in relation to each other, for the purpose specified. l

2. The guards J, springs K, as arranged, in combination With the apron E, and in relation to the frame A and spreader B, in the manner as and for the' purpose set forth.
